What are High-Index Lenses?
The lens index tells you how well a lens bends light. High-Index Lenses bend light more effectively, so they can be thinner, lighter, and more comfortable to wear.
What makes them exceptional:
- Light & Thin Profile – High-Index Lenses are thin and lightweight, providing a sleek appearance and comfortable fit.
- Clean Frame Finish – Slimmer edges make these lenses compatible with a wider range of frame styles, including rimless and semi-rimless designs.
- Natural Appearance – These thinner lenses create a more natural look by reducing the "bug-eye" or "magnified" effect often seen with standard lenses.
- No Color Fringing – High-Index Lenses help keep your vision clear and sharp, with less color distortion and cleaner edges.
